This illustrates the use of rdesigneur to build a simple dendrite with
spines, and then to resize them using spine fields. These are the
fields that would be changed dynamically in a simulation with reactions
that affect spine geometry.
In this simulation there is a propagating reaction wave using a
highly abstracted equation, whose product diffuses into the spines and
makes them bigger.
